Abstract (en)
A method of drilling through a masonry structure 20 includes the steps of providing a drill 10 and using the drill 10 to drill a bore 18 in the masonry structure 20. The method also includes a step of providing a reaction member in the form of a lever 28 and causing engagement of the lever 28 with the masonry structure 20 and with the drill 10 within the masonry structure 20 such that the lever 28 may provide a reaction force to assist the movement of the drill 10 through the structure 20 as it drills the bore 18. <IMAGE>
